7. Rice, and By Products, Buckwheat, and Barley. —The hand-sep¬ 
arated portions of the rice plant, the compositions of which are pre¬ 
sented under this head, were made from a large bundle collected by 
Mr. McCarthy near Wilmington at the time of cutting. The parts 
of the plant and milling products were obtained from the National 
Rice Milling Company, ot Wilmington, N. C., through the courtesy 
of Mr. Norwood Giles, the general manager. Of the milling prod¬ 
ucts, the flour or meal is the first portion taken off the grain by 
the pestles, while the “polish” is an inner layer, removed in the 
process of polishing the grains. This table furnishes data for com¬ 
paring the composition and feeding value of parts of the rice plant 
as separated in manufacture, and as separated by hand, though it is 
to be remembered that the samples separated in the two ways were 
not from the same field. Of course the products from the mill are 
the only ones of commercial importance, the hand-separated parts 
being of interest merely in showing the composition of the parts as 
they actually exist in the plant, and not mixed with other portions. 
The analyses of rice straw show it to be fully equal in feeding 
value to oat straw. It contains more protein, a little less fat, and 
about the same amount of nitr< gen-free extract as oat straw. The 
rice chaff, however, is markedly inferior to either of the above. The 
whole rice grain is, in a high degree, a farinaceous food; starch 
makes up fully three-fourths of its weight, but it also has a fairly 
good percentage of protein. Rice “ flour or meal,” being the first 
portion taken off the grain, is more or less contaminated with chaff, 
and will vary in composition accordingly. Its analysis here shows 
it to be a good carbonaceous food resembling corn meal, but of less 
value. The average composition of oats and the composition of the 
sample of “ rice polish” presented here do not differ materially. 
The “ polish ” contains about the same amount of protein, less fat, 
and more nitrogen-free extract than oats, and is consequently a 
splendid food. 
The buckwheat and barley plants, the compositions of which are 
also showm, were obtained from specimens on exhibition at the 
Southern Exposition in 1891. The grain was full ripe, and hence 
the analyses do not show the composition of the plants, as they 
would ordinarily be cut to feed as a whole, but as harvested for separa¬ 
ting the mature grain. 
8. Okra Pods and Seed. —The composition of okra hulls and seed 
is shown in the table. The seed are rich in protein and fats, while 
the hulls are low in their content of these substances. The propor¬ 
tion of hulls and kernels in the sample separated by hand for analy¬ 
sis were: pods, 59.5 per cent.; kernels, 40.5 per cent. The composi¬ 
tion as presented in this table is of the whole seed, while the pods 
are the hulls, or outer covering in which the seed grew. 
9/Sunflower- seed —The sunflower has been grown in Russia for a 
great many years, and since 1842 on a commercial scale. There are 
two kinds grown there—one with small seeds used for the produc-
